The developing agent Atomal is hydroxyethyl-o-aminophenol sulfate. It was also used in the May & Baker developer Promicrol. Eventually there was just not enough demand for the chemical and production ceased.
Hydroxyethyl-o-aminophenol sulfate was used in Russia in a manufacturing process for something non photographic, that meant it was economic to produce, when the process ceased in Russiathere was no longer sufficient demand to allow manufacture at a low cost. Photographic use had always been a very small fraction of theproduction.
